Brianna Perry has a treat in store for her fans this Halloween. The “Marilyn Monroe” raptress will drop her mixtape Symphony No. 9 on Wednesday, October 31. The 20-year-old Miami native crouches in all black with painted wings and musical notes behind her on the cover art.

UPDATE: The tape has been delayed until November 20. “My label [Atlantic] has stepped in to make this mixtape a more memorable experience,” she told her fans in a handwritten letter. “I promise I won’t disappoint!!!”
